bumping-biome is a skill for Claude Code, Codex from prisma/prisma-next. It costs 96 tokens per session (379 once invoked), scanned A, a copy of bumping-biome, Apache-2.0.

A repository maintenance guide for updating the Biome code formatter and linter, including its configuration files.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

bumping-biome scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

What it actually says

Bumping Biome Skill

Instructions

  1. Run pnpm up -D -w -r @biomejs/biome@<version> - replace <version> with a specific package version provided in the session, otherwise fallback to latest.

  2. Rename all biome.json files to biome.jsonc and replace the old package version number in $schema with the newly installed package version number from the previous step.

  3. Run pnpm -w lint:fix. Report any issues/regressions briefly.

  4. If there are remaining unsafe fixes following the previous step, offer to run pnpm -w lint:fix:unsafe to attempt to fix some of the issues/regressions.

  5. If the offer in the previous step is agreed, run the appropriate command, and report any remaining issues/regressions briefly.

  6. If there are remaining issues/regressions after the previous step, try and come up with your own suggestions for fixing them and present the plan.

Don't Do

  1. Don't scan for biome versions. If the session doesn't include a specific package version number, use latest.

  2. Don't read the root package.json or lockfiles looking for the current biome version/s. We'll see the change in version numbers in Git anyway.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
